Gehmann 520B-35 Fullbore Front Iris 4.0-6.0
The 520 series front irises are designed for the Gehman 529 Series and the Rightsight front sight assemblies. These large 30MM irises offer an improved field of view, allowing shooters to often see the number boards in addition to their target. The 520 series comes with cross bars, giving the shooter the more traditional aperture appearance and helping to keep the rifle level.
Aperture Range: 4.0mm to 6.0mm
